CORN-DRIER SPUR.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed January 6, 1919. Serial No. 269,924.

To all whom it may concern Be it known that I, Josnrri SMITH BAIN, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in CornDr1er Spurs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to seed-corn drying devices, and more particularly to the drier illustrated and described in Letters Patent No. 1,026,550, issued to Joseph Smith Bain and Benjamin L. Bain on the fourteenthday of May, 1912.

The object of this invention is to improve the construction of the ear-holding prong or spur, so as to permit the use, especially in single spurs, of round wire, and that of an ordinary commercial quality. The improved spur also possesses advantages peculiar to its construction, which Wlll be more fully set out hereafter.

In the manufacture of seed-corn driers applicant has used the type of prong shown in Figs. 3 and 4 of said patent, the one shown in Fig. 5 being not only diflicult to form, but being wasteful of material, inasmuch as the double shank of the looped hook must be about twice as long as necessary, in order to permit hooking over the supporting bar. To secure the best results the prong has been made of flat wire, which would hug the supporting bar snugly, and would not swing sidewise, as would a loop of round wire. This, however, called for special wire, not on the general market, and of a temper stiff enough, fiatwise, to support the corn without collapsing. By reason of this hard temper it has been impossible to make a short enough bend at the loop, w1thout cracking the wire, so that supporting bars as thin as desired could be used. These objections and disadvantages are entirely removed in the improved prong, which will now be described.

In the accompanying drawing, Figure l is a view in perspective showing my improved prong or spur, both single and donble, in position on a piece of supporting bar. Fig. 2 is a plan view showing one of them as seen from the under side.

The supporting bar is preferably of rather thin steel, approximately thick the spur is placed in position.

by about one inch in widtlr, This bar 1 is supposed to be attached to a suitable frame, round, rectangular, or otherwise, as desired. It stands vertically edgewise, as indicated, and requires no machining, except the drilling or punching of holes for attachment to the frame. Along it are set the prongs 2, or {3, which pinch it tightly enough to keep their proper position. In Fig. 1 the first prong at the left is a single one, as seen from the back side. The second is the same, as seen from the front side. The third is a double prong, 3.

Referring to the single prong 2, its pointed tang 2 is supposed to penetrate the butt end of the corn-cob, as indicated by the outlined ear of corn. At 2 is a bend, of somewhat less than a right angle, so that the tang inclines upwardly to hold the ear. A short distance from this bend is a returnbend or loop 2, which should be short enough to barely admit the bar 1 edgewise. That portion of the wire opposite the stem 2 of the loop is formed as an eye 2 the stem 2 crossing it practically in the middle. The eye lies closely enough to the stem so that the bar is pinched snugly by them when This gives the spur a broad, three-point bearing on the bar, and holds it securely against slipping, turning, or bending sidewise.

It is to be noted that the form of the spur is such that the pushing of the ear on the tang tends rather to tighten than loosen the pinch of the spur on the bar.

By bending the wire at 3 and extend ing it as a tang 3 a double-pointed spur is formed with the minimum of labor or material. All the advantages incident to the single spur apply equally to the double one.

The construction admits of the use of a comparatively soft wire, easily bent to the tang, the stem being bent to cross the loop centrally and at a little distance therefrom, whereby the spur may be attached to a supporting bar by a three-point pinching c0ntact.

2. A spur I'or corn-driers, comprising a pair of terminal tangs, an intervening loop formed of the same material as the tangs and a stem uniting the loop With one of the 10 tangs, the stem being bent to cross the loop centrally, whereby the oppositely projecting tangs are supported on a bar by a threepoint pinching contact.

In testimony whereof I aflix my signature in presence of two Witnesses.
